IMPROVEMENT IN SQLDERING-IRONS.

Specicatiou forming part of Letters Patent No. 126,905, dated May 2l,1872; antedated April 30, 1872.

Specification describing certain Improvements in Soldering-Iron,invented by HERR- MAN S. SARONI, of Cincinnati, in of Hamilton andStateof Ohio.

The invention consists in certain improvements upon solderingirons, ashereinafter fully described and subsequently pointed out in the claim.

Figure l of the drawing exhibits a-longitudinal section'of thesoldering-iron and han d le with my improvement applied thereto.

2 is my carbonic=acidgas generator shown in section.

A A represents the compound handle and reservoir, having the stop-cock Bandlill-screw C. F is a tube having apertures Gr Gr, and passing throughthe handle A A at the lower, but iush With the upper end. E is a rod,which passes through the packing in the top of the said tube, and istapered at the end to form a conical valve, e. H is a tubular vaporizer,provided With avalve-rest, h, and fitted around the tube F. L is thesocket of a soldering iron, provided with aperture m at the rear andopenings u near the front end. It thus becomes a compoundsocket-and-combustion chamber. Into this socketis inserted theprojectionK of the vaporizer. P is `a: solderingiron, which is detachably fastenedby a setscrew, O. A is a chamber provided with tube r having cock e',and a neck, a', having cock c, as shown in Fig. 2. Attached to and abovethis neck is chamber B', having tube with cock d.

The mode of operation is as follows: Into chamber A is poured a solutionof bicarbonate of soda, and, the cock c being closed, there is alsopoured into the chamber B a solution of tartaric acid. The intermediatecock c being again opened, these two compound elements form a chemicalcombination. In the reaction that-follows carbonio-acid gas is 'one ofthe products. After the handle-reservoir A is partially filled withhydrocarbon,the ll-screw C replaced, and the valve e forced into itsseat h, the stop-cock B is opened, carbonicacid gas is forced into thereservoir A A until a con- Siderable elastic pressure is superinducedupon the county the fluid itself. The cock B is then shut. The effectofthis is to express the Huid through holes G G into the tube F andagainst valve e. This valve being removed to a greater or less degreefrom its seat, the fluid at once rushes into the vaporizer H, which hasbeen previously heated 'to a proper extent The minute stream'ofhydrocarbon is at once transmuted into vapor and passes into thecombustion-socket L. Here it receives a supply of oxygen through hole onand becomes inamed. Through the scattered holes n additional air isintroduced to increase and complete the combustion and impart thenecessary heat to the bit l). The vaporizer requires from an outsidesource but the imparta-tion of heat 4sufficient to commence thecombustion, and

will thereafter automatically receive from the combustion-socket Litself all the heat necessary to perform its function as agas-generator.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination, with soldering-bit P., of a combustion-socket, L,provided with apertures mm, and connected with a vaporizer, as and forthe purpose described.

2. The combination, With a soldering-iron handle, A, serving as ahydrocarbon reservoir, of an apertured tube, F, passing therethrough,and the tubular vaporizer H, arranged to operate together, as specitied.

3. The combination, With a soldering-iron socket L m n, vaporizer H, andtube F, ot' a hydrocarbon reservoir in the handle A provided with agas-induction cock B, whereby the necessary degree of elastic force toexpel the tluid in the reservoir can be introduced thereinto and storednp before the soldering-iron is applied to use.

et. The carbouic-acid generator A B c l e, combined with a hydrocarbonreservoir, to furnish the elastic carbonic-acid gas at the time, in themanner and for the purpose specified.
